Train wheels are good. One wheel with half the axle is what a couple

Another option are Crusher Cones, inner or outer, made of manganese
steel, from rock crushers. About 1000 lbs I believe. Some other
friends of mine use them. I'm not sire where he got them, he's had
them for years.

Perhaps Paul Hashem's Scrap Yard on Brookland St. in Sydney could
help. (902) 564-6346 They may have other suggestions.


At the Halifax Boat Show in February, a local firm was selling concrete
anchors. Since I trailer sail I wasn't interested at the time.
I believe I still have the show program somewhere and could look if
anyone is interested.

I accept and thank you for the offer, especially since I'm in Nova Scotia.

a fifteen foot tall statue of elvis, especially if it had his guitar
sticking out on both sides.

on a serious note, i thought that most moorings were poured concrete,
poured right on the spot using whatever kind of form you can make/find.
concrete cures just fine under water once it's been poured, and i'm
sure concrete is easier to deal than a fifteen foot tall statue of
elvis.

a spit serving as immediate breakwater.

Alternative suggestions to a mushroom would be appreciated.

My understanding is that concrete loses a lot of it's 'weight' in water,
whereas steel/iron do not and given the recent hurricane rash I'd prefer
all I can reasonably get. Plus I'm not in an area catering to such
services as installing moorings, for example.

Gratefully,
Courtney

Wouldn't you know it...That program sat around since the middle of
February, and I must have thrown it out last week when I came across it.
I went to the show list of exhibitors (floor plan doesn't seem to be
available) see ** http://tinyurl.com/e6lfm **
and I'm pretty sure it's 'Good Mooring St. Margarets Bay Inc.'

correct on the "losing it's weight" in water ...

sal****er is 64 lbs per cu ft (displaces 64 lbs per cu ft)

per my pocket ref on material weights (any typos are mine)

cast iron 450 lb/cu ft

portland cement 100 lb/cu ft
mortar cement 135 lb/cu ft
gravel concrete 150 lb/cu ft
limestone w/Portland concrete 148 lb/cu ft

marble 160 lb/cu ft

so, water will displace 64 lbs of an item, so cast iron has a bottom
weight in salt water of 386 lbs per cu/ft

the different cement mixes are 36 to 86 lbs per cu ft when in the
water

I've seen both cement and marble slab moorings in this area ... in
blocks (not formed to dig) and while they tend to sink in over time
depending on bottom composition. I've also seen them move to shore
during a storm.

I personally wouldn't use a block without adding a mushroom to the
works ... the block would prevent the mushroom from lifting, the
mushroom would keep the block from moving.

note: I am not a ground tackle expert ... I have used the weight
formulas to determine lift bag requirements or drums to perform uw
lifts and recovery.

Steel has a higher density than concrete so it takes more concrete to
make a proper mooring. That said, concrete mooring blocks are quite
common and relatively cheap. You only need about 6 cubic feet to make
a 2,000 lb block which is plenty of weight even allowing for the lower
density. Any concrete plant or competent "do it yourselfer" could
make one for you at low cost. Some concrete plants make them up out
of their excess production and may have a few laying around. Typically
a loop of 3/4 inch chain or wire rope is cast into the block as an
anchor point.

Unless you own a floating work barge with hoist, you will need
professional assistance to transport the block and plant it.

maybe you could get it into a cheap wooden dingy, tow it out to where
you want it, and then use large amounts of 4th of july fireworks to
"dramatically" plant the mooring on the bottom. if enough explosives
were involved i'd pay 5$us to see that lol ...

The way that old Enoch Winslow did it was to back the truck down to the
water at low tide. and dump it.
then he would bring two wooden skiffs with a couple 6x6 lashing them
together, hanging the weight between them.
The chain was attached to the logs by a thick rope. At high tide he woud tow
the skiffs, chain and mooring bouy to where the mooring was to be set. At
the proper place his helper would take an axe to the rope.
